Looks like low grade to me. Lots and lots of junk and no visible gold. Not sure that is even silver. I would probably pass on taking a risk higher than $0.15 per pound.

Those boards are nickel etching.
Given that pure nickel is trending between 1.75 and 2.25 a pound... low grade isn't off at all. There's less than a quarter ounce of nickel on the largest board.
It's while many of the components have p/m in them... it's also about the recovery yields and how much cost is involved in recovery.

Boards like these take a lot more resources to refine than something like ram.

However if you'd like to buy them from me at the highest rate I'd be happy to sell you a few hundred pounds.

First i will apologize for my writing, english is not my first language, i live near Russia.
Second i want to say that the soviet bords was not nikel etching, they use silver, silver-palladium aloys and SnPb alloys.
The fingers of old soviet bords, they are Ag/Pd alloy, not tin like the others.
All the green and orange capacitors contain Pd, and some series have Pt, the grey small switches contain Pd and so on.


Thank you

I will apologize if I jumped down your throat. You're reply was to the owner.
I agree that many Russian boards have massive amounts of pm... what was posted here are not "Serbian" made boards. They're Kazak. And nickel.
I've been repairing and working with computers since the late 80s.
Aside from custom super rigs i specialise in old and foreign tech.
While anyone makes mistakes myself included, i stand by my assessment. They're nickel etch boards, likely from an entertainment device, or an advertising/display unit. In all likelihood a vending device. Which was common in Mother Russia's union states during the late 70s through today.

Through reverse engineering and outright (thought warranted) theft I've always stood by Soviet tech as some of the best (and also most valuable) examples of digital innovation. Somari...for example.

I may not always get boardsort's grades exactly right but I do always know my material. I'd bet a new ($800) i7 they're nickel. and pm content... anyone here the last year or so will tell you, I'm never wrong.

I just want to say my opinion, I am a refiner, and being so close to Russia I have a lot of they're stuff, also bulgarian, romanian etc.
And trust me, is not nickel, is Sn/Pb or silver alloy

Best regards,
Ovidiu

It is a matter of familiarity of this kind of material. Northern Ohio does not see this kind of material, so I can understand Boardsort not willing to take on the risk.

A number of my refining friends have experience in this kind of material and this kind of stuff is what they drool over. If you can confirm the source this kind of material has an extremely high PM content. But knowing the source is much different than taking someone's word for it. If those are the right components, the price per pound refiners will pay will make your jaw drop... but if they are not....

Depending on the quantity you have, I would try to find a refiner for this material... Bayblend is right, this is good material, don't let it go for cheap (at least not for $0.15/lb). Unfortunately, if you only have a few pounds then you probably wont be able to get much for them. How much of this material do you have?
